Semiconductor device cooling structure - includes finned base with slots for contact strips, and securing bolts holding device across them
Radiation detector consists of low capacitance photodiode - with several small diodes on semiconductor substrate near to scintillator
Electronic water descaler - with pulse generator controlled by varying water outflow rate
Halogenated mercapto-ethyl-sulphone and mercapto-vinyl-sulphone derivs - useful as algicides, fungicides, bactericides and aquatic herbicides
Bifurcated electrical connector pin - has either semicircular or chamfered profile where separated parts of pin meet
Fatigue damage to mechanical element measuring appts. - assesses change of resonance frequency and damping of tested structure and compares results with those of structure unused
Plug for deep undersea pipeline with pyrotechnic gas-generating charge - which brings about sealing off against high pressure, preventing flooding of pipeline in case of accident during laying
Direct heating of large vol. of liq. by burner flame - to obtain high thermal efficiency, esp. when liq. is used for surface treatment of metals
Sprung metal retaining washer - has corrugation in two planes and gap to form resilient friction bond
Bridge concrete road slab expansion joint seal - has elastic unit between rearward reinforced top parts of vertical plates
Agglomeration of ore mixts. on travelling sintering grate - where ore mixt. is baked as two separate layers, and coal may be used to replace coke in mixt.

Bonding metal parts for prodn. of reinforced plastics materials - using thermoplastics binders, esp. polyamide and polyvinylidene fluoride
Portal frame stand for vending display or drapes - has height adjustable rail with holes for square end returns of pivotable cantilever arms
Leather hand-bag with clasp - uses twin inter articulating portal frames to define opening with frame legs inside edge bar ends
Irrigator with hose reel - has positioning wheels holding races against supporting rollers to prevent axial movement
Growing tree seedlings in bottomless conical pots - which are supported above surface, with air gap between bottom of pot and surface to discourage root growth through bottom of pot
